Abstract

Tube de guidage pour ensemble de combustible nucléaire. Il présente un ensemble de protubérances 41 qui résistent au déplacement de la grille d'entretoisement 23 sous l'effet de l'écoulement de réfrigérant et qui constituent un moyen secondaire de support de l'ensembe de combustible pendant les opérations de pose et de dépose dans le coeur. Applicable de manière générale à la construction de coeurs. nucléaires.Guide tube for nuclear fuel assembly. It has a set of protuberances 41 which resist the movement of the spacer grid 23 under the effect of the flow of coolant and which constitute a secondary means of supporting the fuel assembly during the installation and removal operations. in the heart. Generally applicable to the construction of hearts. nuclear.
